Lovin that pic of mk1, bye bye sierra and mk 2 = hello hot x flowed mk1!! I run a 69 mk2 zetec cortina , a 66 Oldsmobile 442 with a 6.6 V8 in and have a little 1.2 corsa as a daily that does 40-45 mpg, not flash but cheap as chips to run-tax and insure. Think whatever decision you take you will regret some way or another mate. Good Luck!
